The Fight for Purity in Semiconductor Fabs Begins at the Chemical Manufacturer

To meet increasing sensitivity to contaminants in integrated circuit (IC) manufacturing, semiconductor fabs have begun looking to their chemical suppliers to adopt new contamination control standards that improve quality and assist in reducing wafer defects. Each material has several touch points along the chemical manufacturing, storage, transport, and delivery journey that could add or generate contaminants. Semiconductor fabs seek assurance from their materials suppliers that they will minimize opportunities for contaminants to end up on a wafer (Figure 1).
